What role does collagen and elastice fibers play in the skin?

Collagen and elastic fibers are essential structural proteins in the skin that contribute to its strength, elasticity, and overall integrity. Collagen provides a framework that supports the skin and helps resist stretching, while elastic fibers allow the skin to return to its original shape after being stretched or contracted. Together, they maintain the skin's firmness and resilience, playing a crucial role in its appearance and functionality. Aging and environmental factors can lead to a decrease in these fibers, resulting in wrinkles and sagging skin.
